PATENT OFFICE.

SELF AND M IGHAEL LEHMAN, OF SAME PLAGE.

IMPRovED RocKi-:RFOR FURNITURE.

Specilcaton forming part of Letters Patent No. 46.302, dated November 29, `1864.

Toa/Il whom t may concern:

had to the accompanying drawings, making part of this specification.' V

M y improvement is applicable to the rock; ers of cribs, chairs, hobby-horses, rockingchairs, Src.; and it consists in a peculiar manner of attaching to-the under side of the rock ers a strip of india-rubber. 'i

Figures l and-2 are longitudinal sections of rJkers provided with my improvement. Fig. 3, is a transverse section. l ,I

The rocker A is formed with a dovetail groove 'extending longitudinally along its sole or bottom edge '.to receive and holda strip, C, of india-rubber, (caoutchouc,) which is further secured by screws a and b. Bosses D on t ne ends of the strip prevent the overturning otthe crib, and byptheir elasticity increase the rocking action. .l

Several decided advantages result fronrmy rubber attachment, for example: First, the crib or other furniture Amay be rocked with impunity and yet willretain its exact original 'location upon the door; second, the carpetis not subject to be worn by projecting angles or splinters on the lower edges of the rockers lor by upturned edges of the 'oor; third,

such rockers may be -.usedon an uncarpeted door `without noise or jar; fourth the elasticity of they rubber facili-tates the rocking action and renders it more free and a reeable.

I kam aware .that gum-elastic ligas before been applied to the soles of rockersgbut, Havingvthus described my invention, what I claim as new-therein, and desire to secure by Lctters-1atent,pis A 'The combination of the dovetailed grooves B', rubber stripsG, bosses D D, and screws b 4vb, all constructed, arranged, and employed in the manner and for the purpose specified.

i In testimony of which invention I l.hereunto set my hand.-
